LOCOMOTIV'E STRUCTURE.

Application led J'une 21, 1924. Serial No. 721,408.

To all 'whom t may concern.'

Be it known that I, HARRY M. PFLAGER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Locomotive Structures, of which the following is a specification, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to railroad rolling stock and consists in an improved air pump mounting and preferably in a pilot beam construction adapted to accommodate such mounting. n

The object of my invention is to mount the air pump as near as possible to the front of the locomotive, thereby relieving the drivers of some weight and also utilizing space which yis not required for other purposes.

A more particular object of my invention is to utilize the pilot beam for carrying the air pump and in my preferred construction l also desire to provide the pilot beam with. integral flanges or brackets for supporting the air pump.

An additional object of my invention is to shield and protect the air pump in its forward mounting.

Inthe accompanying drawings which illustrate my invention- Figure 1 is a top view of a pilot beam showing the air pumpmounted thereon.

Figure 2 is a vertical transverse section on line 2--2 of Figure 1.

Figure 3 is a front elevationof a part shown in. Figure 2. i

Figures 4 'and M5 are sections corresponding to Figure 2 but illustrating modifications of my invention.

The pilot beam 1 may be of any usual type but I prefer to utilize a one-piece casting provided on its rear face with pads 2 and also provided with integral brackets 3 having reinforcing flanges 4 and provided with pads 5. Pads 2 and 5 are adapted to mount the fianges 6 and 7 provided on the steam cylinder 8 and air cylinder 9, respectively.

The body of flange 3 is preferabl perforated with one or more openings 1() etween its pads 5 and` flanges 4 for the purpose of permitting the free passage of air t rough the bracket and to and around the air cylinthe air cylinder could be located on the other v side.

In the modification shown in Figure 4 the beam 11 is provided with brackets 12 and 13 extending upwardly and downwardly, respectively, from the rear wall of the beam and each, having reinforcing flanges 14 and pads 15 for mounting the cylinders 16 and 17. lVith this arrangement, one of the cylinders projects above the top of the beam and the other cylinder projects below the bottom of the beam, instead of the entire projection being below the beam as shown in Figures 2 and 3. Either or both of the flanges may be provided with openings 21 to permit the passage of air therethrough and the forward and rear walls of the body of the beam may be provided with openings 22 for the same purpose.- Similar openings 10 are shown in the body of beam 1 in the preferred construction.

In the modification shown in Figure 5, the ent-ire projection of the cylinders is above the beam, the bracket v18 extending upwardly from the top of thebeam 19 and provided with reinforcing flanges 20. The bracket is perforated as indicated at 23 for theV circulation of air about the cylinders and openings 24 for the same purpose are shown in the body of the beam.

Another modification of my invention is described and specifically claimed in my copendin application Serial Number 721,409, filed o even date.

In all the embodiments of my invention, it will be understood that the cylinders may be connected with the steam supply and with air reservoirs by the usual piping, a1- though the latter is not shown in the draw- It will be noted that the brackets shield the cylinders throughout the extent of the projection of the latter beyond the beam and reduce the likelihood of injury by collision of the pilot or beam with relatively light objects. However, the brackets may terminate at the pads if it is preferred not to provide a shield for the full length of the cylinder, and various other modifications in the details of my invention may be made without departing from the spirit thereof as claimed.

I claim:

l. In a locomotive, a pilot beam, a bracket thereon, and an air pump mounted on said pilot beam, said beam and bracket being perforated to provide free circulation rof air around said pump.

2. In a locomotive, a pilot beam, a bracket on said beam, and an air pump mounted on said bracket and shielded thereby.

3. In a locomotive, a pilot beam, a bracket on said beam, and an air pump including an air cylinder mounted on said bracket, said bracket being Vperforated adjacent said cylinder to afford free circulation of air about said cylinder.

4. In a locomotive, a pilot beam, a bracket on said beam, and an air pump comprising a steam cylinder and an air cylinder, axially aligned, mounted on said pilot and bracket and shielded thereby.

5. In a locomotive, a pilot beam, a bracket on said beam, and an air pump comprising a steam cylinder and an air cylinder, axially aligned, mounted on said pilot and bracket and shielded thereby, the mounting element for one of said cylinders being perforated to afford free circulation of air about said cylinder.

6. In a locomotive pilot beam, a perforated bracket extending a substantial distance beyond the horizontal plane of the bea-m body and adapted to mount an air pump element, and a reinforcing element extending from a portion of said bracket spaced from said beam to a part of said beam spaced from said bracket.

7. In a locomotive pilot beam, an integral bracket extending' downwardly from the rear of said beam and adapted to mount an air pump member below the level of said beam, and reinforcing elements extending from the lower edge of said bracket to the front of said beam.

8. In a locomotive pilot beam, an integral bracket extending downwardly from the rear of said beam and adapted to mount an air pump cylinder below the level of said beam, and spaced reinforcing elements extending from the lower edge of said bracket to the front of said beam, said bracket being provided with a substantial opening between said elements to afford free circulation of air to said cylinder.

9. In a locomotive pilot beam, a perforated bracket extending a substantial distance bcyond the horizontaly plane of thel beam body and adapted to mount an air pump, and a. reinforcing element extending from the lower portion of said bracket to a part of said beam spaced from said bracket.

l0. In a locomotive pilot beam, an integral flange extending a substantial distance beyond the horizontal plane of the beam body and adapted tomount an air pump, and rein'- forcing ribs bracing said flange transversely of the beam.

1l. In a locomotive pilot tegral flange extending a substantial distance beyond the horizontal plane of the beam body and adapt-ed to mount an air pump cylinder, said flange being provided with one or more substantial perfor-ations to afford free circulation of air about a cylinder mounted thereon.

12. In a locomotive flange extending a substantial distance beyond the horizontal plane of the beam body and adapted to mount an air pump cylinder, said flange being provided with one or more substantial perforations to afford free circulation of air about a cylinder mounted thereon, and cylinder attaching pads at the sides of said perforations.

13. In a locomotive, a pilot beam, and an air pump mounted on said beam at the rear thereof, and openings in said beam to permit the free circulation of air about said pump.

In testimony whereof I hereunto allix my signature this 28th day of May, 1924.
